Fatented Oct. 24, 1933 J OKE BUZZER Alberi; Weill, Nuremberg, Germany Applicatic1i Februa ry 23, 1933, Serial No. 658,134, ami in Germany January 25, 1933 2 Claims. (Cl. 272-.-27)

My invention relates to an improvement ci the mechanical juke buzzer, described by Lefiters Patent No. 1,845,735, in such a manner thai instead of the known iccking lever adapted tc coact With the buzzer lever, a slide member is arranged Within a bcx-shaped casing. The cuter end ci said slide member projects through an epenng ci the casing and is fcrmed as a constituent pari; fitted to apparenty serve for opening the casing. With the intenticn to open che casing, a pressure is exerted on the prcjectng part ci the slide member, tnis member being 1ncved within the casing in such a manner that the buzzer lever is reieased.

My invention is shcwn by wa.y or" example in che annexed drawing, in which Fig. 1 is a perspective view or" the casing,

Fig. 2 a vertcai longitudinai section,

Fig. 3 a similar secticn turned 90 degrees,

Fig. 4 a pian view With upper casing secticn be ing taken away, and

Fig. 5 a detail view.

The cup-shaped casing sections a and I) forming a box, are relatively rotatable about the coaxial rivet 0. The spring d is situated Within the upper secticn casing a sud engages with its inner end the spindle e supported by the ccaxial rivei; c. Said spindle is provided With the tccthed wheel 1, the spring d being held in position by the carrying member g. Hithertc,the ccntrivance is the same as described in Letters Patent No. 1,845,735.

Acccrding to my invention, a disk member h is arranged Wthin the 1cvver casing secticn b which supports on its underside 2:, slide member n projeeting With its cuter end 1 thrcugh an opening of the casing. 'Ihe disk membnh is provided With a slot i thrcugh which the inner end ci sad slide member is prcjecting in the form of a lookng nose s coacting With the buzzer lever k. Said buzzer lever is pivotally mounted, a,s hitherto known, between its ends ai; m 011 the disk member h md, ha.ving twc teeth 12 and 0, to engage the vrhee1 f, so that upon rctaticn or" said wheel the buzzer lever is oscillated.

The slide member 1o being provided With a slot in its middie part fo'r passing the rivet 0 is supported on the under side ci the disk member h by means ci a guide t and carries 21, pin 1:, aga,inst which resiss a spring w placed on the under side ci the disk member h. The guide t has a, slot u, through which the coaxial rivet c passes and the pin 1) moves. On the upper side of the disk member h the buzzer 1ever la is journaled.

On the outside at o: ci the lower casing section b an imitated hinge s fitted to give the appearance tha.t the two casing sections are mcvably ccnnected.

The drivirig spring 61 is wcund by rotating the two casing s-ecticns a and I) against cne another abcut the coaxial rivei; c, as hitheruo kncwn. The 3 slide member p carrying the pin 1; is held by the ci che spring 10 in such a, pcsiticn thai; its enter end? projects beyond thecasing as shown in Fig. 1. This prcjecting end 1' ci the slide member p represents a ccnstituent pari ci the whole 5 and serves icr opening the casng by pressing upcn ii). Thereby the locking nose 3 on the inner end of the slide rnember p holds th e buzzer lever la in its locking position.

With the intenticn to open the casing a. pres- 70 sure by band is exerted upon the projecting end r, and the sfide member p is moved in such a manner that the lccking nose s releases che buzzer lever lo, whereby the vibrating cperaticn 01 che 1a/cter by rotaticn ci t'ne toothed wheel is cbtained. Terminating tne pressure upon the prcj ecting arm the siide member p returns to its ncrmal position, owing to the nfiuence ci ti1e spring w, and the lccking nose s causes again che stcpping ci the buzzer lever la.

Iaving now fully described my invention, wha.t I cla,im is:

1. A joke buzzer conssting of a casing with two relatively rotatable sections ncluding a spring actuated buzzer lever end a locking member to 5 contrcl cperation therecf, comprisng a slide member prcjecting laterally through the casing to fcrm a ccnstituent part of the whole, a lccking nose formed at the inner end of said sfide member to engage With said buzzer lever and a spring for actuating said slde member to cause engagemeni; With said buzzer lever and to move said slide member outwardly thrcugh the casing.

2. A joke buzzer ccnsisting of a casing with two reiativeiy rotatable secticns including a spring actuated buzzer lever end a lccking member to contrcl operaticn therecf, comprising a disk member arranged wth the iower casing section, a slide member projecting laterally thrcugh the casing and being arranged on the underside ci said disk member, a spring for actuating said slide member to cause engagement With said buzzer lever, a. guide mounted on the underside of said disk member to receive said slide member, a. slot provided in said disk member and a lockng nose formed at the nner end ci said sfide member to prcject through said slot and to engage with said buzzer v lever.
